As a divinatory line, six at the first place of The Wanderer reads within the hexagram's overall concern with some small attainment and progress for the stranger who is firm and correct as he travels. The line occupies a place that does not match its own nature in the classical doctrine that odd places favour a firm, yang line and even places favour a yielding, yin line. Its own text, that the wanderer occupied with mean and trivial things, bringing on himself the calamity that follows, is the particular fortune assigned to this one stage of the situation, not to the hexagram as a whole.
The first line corresponds by classical convention with the fourth line, and the two correspond here, since one line is yin and the other yang. Read together with the trigram it belongs to, Gen in the lower position of the figure, the line marks the opening of the situation, before the trigram above it has any part in the reading, one stage in the six stage movement the hexagram traces from its first line to its last.
A change at this line, from yin to its opposite, is the mechanism the tradition uses to move from one hexagram to another. Flipping the first line of The Wanderer turns Gen into Li while the other trigram, Li, stays as it is, which yields The Wanderer's changing partner, The Clinging (King Wen 30), the hexagram this line is recorded as transforming into.
